WHEEL BLOCK AND DERAILER.

Application filed June 6,

1 aZZ whom it may concern:

Be it known that I, THOMAS H. Eman- BLUTE, a citizen of the United States, re-

siding at Pittsburglnin the county of A110;

from the working face of the mine, that is,

there is an up grade toward the working face. However, this is not always possible, and in many instances the floor inclines downwardly toward the working face. lVorking at such a face is exceedingly dangerous if the coal cars are not carefully handled, as an empty or loaded car, breaking loose or getting beyond control in the working, is apt to crush a miner at the working face. While the rules of most mines generally require that a workman erect some barrier across a track for his protection, this rule is apt to be neglected or the barrier improperly placed.

The present invention is particularly designed for use in workings going to the dip, although its use is not confined to installation at such places.

The invention has for its principal object to provide a device which may be placed on a rail and is intended to provide a block against which the carwheel will come to hold the car against further forward movement, but which is so shaped that, if the car is coming with such speed that it will climb the block, it will be derailed in a given direction.

A further object of the invention is to provide a readily portable structure espe cially designed for temporary installation, so that it may be readily moved forward as the working progresses.

The invention may be readily understood by reference to the accompanying drawings, in which:

Fig. 1 is a top plan view of my invention applied to a rail;

Fig. 2 is a side elevation thereof;

Fig. 3 is an end view from the uphill end of the device; and

Figs. 4 and 5 are views similar to Fig. 3,

1923. Serial No. 643,781.

showing modified'forms of rail clamping means.

In the drawings, A designates the rail having a head a, a web 6, and a base 0.

The blocking and derailing member 5 comprises an integral body 6 having a flat surface adapted to rest on the top of the rail. This body 6 has a rounded surface 7 on the uphill side thereof, adapted to provide a block against which car wheels may abut. Offset to one side of part 6 and integral therewith, is a flange 8, a groove 9 being formed at the uphill end of the block between the flange and the body of the block. The groove is of decreasing depth, and curves across the body of the block, which body tapers down at 10. The flange 8 also crosses the block. Part 7 extends a slight distance in advance of the uphill terminal portion of flange 8.

The arrangement is such, therefore, that if a car, coming down the track to which the invention is applied, has sufficient momentum to force it to climb abutment 7, then the flange of the wheel will be guided by flange 8 in groove 9, directing the car to one side to derail it. If the car is only moving at a reasonable speed and is under control, then portion 7 will function as a block to hold the car in place while being loaded.

Depending from the offsetpart of the block are integral rail web engaging parts 11. Extending down from the other side of the block is an offset arm 12 having a hook 13. A wedge block 14 cooperates with this hook when driven between arm 12 and the web of the rail to firmly clamp the derailer device to the rail.

In Fig. 4, the construction of the derailer is the same as that described in connection with Fig. 1, but, instead of arm 12 being shaped as shown in Fig. 3, an arm 12' is provided which slopes downwardly and outwardly, terminating in hook portion 13*, through which passespin 13", providing a pivot for a cam like wedge plate 14 having a web engaging portion 14*. This construction eliminates the necessity for a detached wedge block.

In Fig. 5, the structure is especially designed for use with a rail turned sideways, as is frequently the case at the working face of a mine.

In this form, the body is not changed, but the rail clamping structure is somewhat different. Formed below the offset part of the body 6 is a rail engaging member 15. On the other side of the body is a depending integral part 16 to which a cam plate 17 is pivoted by pin 18. This plate has an eccentric edge 19 adapted to be forced into clamping engagement with the flange of the rail, as shown.

In both Figs. at and 5, I have shown a lug 20 on the pivoted cam plate adapted to engage the floor of the mine and assist in holding the plate against movement.

Various other changes and modifications may be made in the construction of the device within the contemplation of my inven-' tion and under the scope of the appended claims. 7

I claim as my invention:

1. A combined block and derailer for use on rails and comprising a tread block having a blunt forward end, a flat under surface for resting on the head of a rail, a fixed rail engaging abutment on that side of the block that goes to the inside of the rail for holding the block against transverse movement outwardly, a derailing guide on the block having its forward end also at the inner side of the block rearwardly of the blunt forward edge of the tread, said guide extending diagonally across the tread block, a lug depending from the side of the block that goes to the outside of the rail, and an adjustable clamping means engaging the lug for cooperation with a rail to hold the device in place.

2. A combined wheel block and derailer for use on rails comprising a body having a tread portion whose forward end is relatively high and blunt, a derailing guide associated with the tread and providing a v channel whose forward end is disposed rearwardly of the blunt end of the tread portion, the under face of the tread portion be ing fiat to rest on the head of the rail, said guide having its forward end below the flat portion of the tread portion. the channel of the guide at its forward end also being below the under surface of the tread, said guide extending diagonally across the tread rearwardly of the forward end thereof.

In testimony whereof I affix my signature.

THOMAS H. EDELBLUTE.
